Hi, all. I posted this as a comment in another thread, but it honestly deserves a thread of its own.

Brineshrimpdirect.com has a really neat hatchery dish for BBS that does not require an air pump. And for a limited time, they give you an entire spice-jar-sized batch of BBS eggs when you buy it. Just the BBS eggs alone are worth more than the price of the hatchery.

I bought this and am really happy with the hatchery, though you do have to leave the light on in the room for the shrimp to swim toward the center receptacle. It's really a great deal for breeding!

I wish I understood, to be honest. I'm not saying it's better than other methods of hatching, but it does work, and without a pump.

It has somewhat of a maze piece you place inside it, and the only point of light is the collection basket in the center. I assume the shape of it helps hold heat in, and the shrimp gravitate toward that collection basket as they hatch, because it's the only point of light.

But even if you didn't want the hatchery, the eggs are honestly worth the price.

This is a sort of old school hatchery I saw some killie people discussing on another forum. People liked it because you got a very easy separation of eggs from the hatched shrimp, because the BBS would have to swim through the maze towards the light.

However, the consensus was that it does not give as high a yield as the more common method of hatching and several members said that if they had a large amount of fry to grow-out then it did struggle.
